How to figure out the legnth of a track from blender

I figured out a simple way to see how long your track is from within blender, so you don't have to race the track to see how long it is.
accurate to within 5 seconds.

you take a curve and "fit" it to your track. Add a plane with an array and curve modifier (using that curve), apply them, take the number of faces and divide by 11.5 and that is your length in seconds
